1. Write C statements which tests to see if input file has opened the data file successfully. If not, print an error message and exit the program. 2. Write C code which will read a line of characters (terminated by a \n) from input_file into a character array called buffer. NULL terminate the buffer upon reading a \n. 3. Write a C program that will get 10 grades of the student from a file. Get the average of the three grades and check each grade if its passing or not. Passing grade is 70. Store all the passing grade to an output file, and store all the failing grades to another output file.

Counting the character occurrences in a file For this task you are asked to write a program that will open a file called "story.txt" and count the number of occurrences of each letter from the alphabet in this file. At the end your program will output the following report: Number of occurrences for the alphabets: a was used – times. b was used – times. c was used – times.... .and so, on Assume the file contains only lower-case letters and for simplicity just a single paragraph. Your program should keep a counter associated with each letter of the alphabet (26 counters) [Hint: Use array] Your program should also print a histogram of characters count by adding a new function print Histogram (int counters []). This function receives the counters from the previous task and instead of printing the number of times each character was used, prints a histogram of the counters. An example histogram for three letters is shown below) [Hint: Use the extended asci character 254]: A…
String data type is not allowed you can make use of CString instead (char arrays with null termination). Write a menu driven C++ program to perform the following four tasks in a single file, if user press option 1 the task 1 get solved and so on: 1. Display the Item_Id of the products which are not available in stock on screen. 2. Copy all the available products data in a separate file. 3. Read the original input file and update the price of each item by 10 percent increase in the original price and save the complete information in separate file. 4. Try to save the information processed in part 3 in the original file by updating it instead of using separate file.
PYTHON without def function Problem Statement Suppose an input file (called "paragraph.txt") contains a paragraph of text. Read in the file and then count/print the number of times the word "book" is in the file. Hint: Punctuation should be ignored, i.e., "book?" and "book!" should increase the count. The program should also be case-insensitive. Sample Input (File paragraph.txt) I have a book. It's called Harry Potter. It's a pretty good book! Do you want to buy my BOOK? Sample Output The word 'book' appears 3 time(s).

The function print_last_line in python takes one parameter, fname, the name of a text file. The function should open the file for reading, read the lines of the file until it reaches the end, print out the last line in the file, report the number of lines contained in the file, and close the file. Hint: Use a for loop to iterate over the lines and accumulate the count. For example: Test Result print_last_line("wordlist1.txt") maudlin The file has 5 lines.
This Python Lab 9 Lab: Write a file copying program. The program asks for the name of the file to copy from (source file) and the name of the file to copy to (destination file). The program opens the source file for reading and the destination file for writing. As the program reads each line from the source file and it writes the line to the destination file. When every line from the source file has been written to the destination file, it close both files and print “Copy is successful.” In the sample run, “add.py” is the source file and “add-copy.py” is the destination file. Note that both “add-copy.py” is identical to “add.py” because “add-copy.py” is a copy of “add.py”. Sample run: Enter file to copy from: add.py Enter file to copy to : add-copy.py Copy is successful. Source file: add.py print("This program adds two numbers") a = int(input("Enter first number: ")) b = int(input("Enter second number: ")) print(f"{a} + {b} = {a+b}") Destination file:…
Q4. Write an algorithm of a program to read from a file. The user should be able to get the option to input the file name. He is supposed to read first 100 bytes from the file. After the reading is done, the file should be closed. If the file is not available, the program should be closed immediately. You should mention "System call" beside each instruction which are supposed to use a system call function. *
File Iteration: Introduction A text file is essentially a sequence of lines. Here is a typical coding pattern for processing each line of a file in turn: Open the file for reading. Use a for loop to iterate over the lines of text, executing a block of one or more statements to process each line. Close the file. Finish processing (print, return, etc.) if needed NOTE: You will need to use this pattern, or some variation of it, to solve the remaining coding problems in this assignment. As the following for loop iterates through each line of the file, the loop variable (`line`) represents the current line of the file as a string of characters. myFile = open("someTextFile.txt", "r") for line in myFile: do something on each iteration do a second thing on each iteration etc... myFile.close() PROBLEM: Read a string from standard input using python. Then, iterate over a text file called "cards.txt" and, for each line of the file that starts with the string read from standard input,…

C++ Programming. Associative and unordered associative containers. Associative containers (set, map, multiset, multimap). • When executing a given task, the input values must be read from a text file. Task : Create a program that deletes a set of elements from a single word of a given string type and creates a second set of elements that consist of a single word, and also displays it on the screen.

Python - Next Birthdate In this task, we will write a program that reads birthdate data from a given CSV file, and given the current date, determines which person's birthday will be celebrated next. Create a function with the following signature: nextBirthdate(filename, date) filename: parameter, which represents the CSV filename. date: parameter, which represents the current date. The function should open the CSV file, read the birthdate data, and determine which person's birthday will be celebrated next, given the current date. The name of the person should be returned. In other words, given a date, find the person whose birthday is next.
